get_drivers

my @drivers = $bus->get_drivers;

Returns a list of Linux::Sysfs::Driver instances that are registered with this bus.

get_device

my $device = $bus->get_device($id);

Looks for a device with the given $id on this bus. On success, it returns a Linux::Sysfs::Device instance, otherwise undef.

get_driver

my $driver = $bus->get_driver($name);

Looks for a driver with the given $name on this bus. On success, it returns a Linux::Sysfs::Driver instance, otherwise undef.
